This application of Google Maps is interesting since most all of the Google Maps mash-ups and applications that have been created using the Google Maps API have been aggregating data from land based locations. This shows that the Google Maps API can also be used for locations at sea as well.

Note: Todd tells me that the ship and her crew are currently in port right now in Honolulu after 11 days at sea so you may not see the ship icon moving very much..
